I never heard of it before, but it looks like some type of medical mission thing? IMO, medical missions are overrated. Why pay hundreds of dollars to volunteer in Africa when you can volunteer at the local soup kitchen or free clinic? It's one thing if you have a legitimate interest in global health and the specific healthcare issues that developing countries face, but most people who go on medical mission trips couldn't tell you the first thing about Kenya, or Ghana, or Nigeria. They just see medical missions as resume builders.
If you're like most premeds, you'd probably benefit more from volunteering in the local community. The average middle class premed probably lives less than a mile from a neighborhood with high unemployment, high crime, high drug use, poor education, and poor access to healthcare. Do you know what it's like to live on food stamps? What it's like to go to a high school with a >90% dropout rate? What it's like to sit in the Department of Social Services waiting room for a full day while trying to get your Medicaid coverage renewed? Most premeds do not, but in med school they will be working with patients who were born and raised in these conditions.
Volunteer at the local soup kitchen and try to get to know some of the patrons well. You will get a lot more out of it than you would from a two week trip to Africa. I'm sure
@Planes2Doc would agree.
Ask around to see if any professor is looking for a research assistant over the summer. Even an unpaid position is better than doing nothing.
